Question

在尝试将ressource字典添加到应用程序的MergedDictionary时，我遇到了解析错误。

System.Windows.Markup.XamlParseException occurred

这似乎指出我的转换器声明出错，但我无法弄清楚原因。

这是我加载的资源

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:Common.UserControls">
    <local:ButtonVisibilityConverter x:Key="PageButtonVisibilityConverter"/>
    ....
</ResourceDictionary>

转换器声明：

namespace Common.UserControls
{
    public class ButtonVisibilityConverter : IMultiValueConverter{
        ...
    }
}

加载字典的代码： ResourceDictionary dictionary = new ResourceDictionary {Source = new Uri（＆＃34; / Common; Component / UserControls / Generic.xaml＆＃34;，UriKind.RelativeOrAbsolute）};

转换器和资源位于同一文件夹中。加载资源的代码位于同一个项目中。

我不知道出了什么问题，因为昨天一切正常，所以我不确定是否因错误引入了更改或是否还有其他问题需要检查？

我已经清除了整个输出目录。

此外，转换器的名称空间声明是由Resharper直接创建的，很少出错。

感谢您的帮助
